We ran ours on 208V, I think we had 4MB; we used a Fuji Eagle drive and a
CDC cartridge drive for disks and a Cipher streamer for tape. It worked
pretty well. The 730, on the other hand, was something of a wimp.
I was offered one when
Sorcim dumped theirs and I refused it. Microprocessor technology was
catching up too fast to consider giving it a home.
It's realllly slow (about 25% slower than the 11/750) but physically
small and only has 5 memory slots for 1MB boards.
Using TU58 as the console boot medium made booting even slower, but if
you copied all the files off of your tape (with EXCHANGE) and built a
new tape (also with EXCHANGE), you could order the files properly and
since the TU58 microprocessor appeared to cache the directory
track(s), loading was then sequential and *substantially* faster.
The 11/730 wasn't so bad if you used it like a single-user workstation.
